Pump motor and washing machine having the same

Abstract

A pump motor is disclosed. The pump motor includes a case; a socket part disposed in a portion of the case and provided with a terminal part thereinside; and a cover part detachably coupled to the case and configured to open and close the socket part, wherein the socket part includes a moisture blocking member configured to block a gap between the case and the cover part.

What is claimed is: 
     
       1. A pump motor comprising:
 a case: 
 a socket part disposed in a portion of the case and provided with a terminal part thereinside; and 
 a cover part detachably coupled to the case and configured to open and close the socket part, 
 wherein the terminal part includes a first terminal and a second terminal protruding from the case, and 
 wherein the socket part includes at least one barrier partitioning between the first terminal and the second terminal. 
 
     
     
       2. The pump motor of  claim 1 , wherein the socket part comprises at least one drain hole provided in a lower portion thereof. 
     
     
       3. The pump motor of  claim 2 , wherein the socket part comprises a plurality of drain holes with the at least one barrier in between. 
     
     
       4. The pump motor of  claim 2 , wherein the socket part comprises an inclined surface inclined toward the at least one drain hole. 
     
     
       5. The pump motor of  claim 1 , wherein the socket part comprises a moisture blocking member configured to block moisture from flowing into the socket part. 
     
     
       6. The pump motor of  claim 5 , wherein the socket part comprises a body part surrounding the terminal part, and
 wherein the moisture blocking member is formed along an edge of the body part. 
 
     
     
       7. The pump motor of  claim 6 , wherein the moisture blocking member protrudes from the body part outward of the socket part. 
     
     
       8. The pump motor of  claim 6 , wherein the moisture blocking member is bent from the body part outward of the socket part. 
     
     
       9. The pump motor of  claim 1 , wherein the cover part comprises a front cover and a rear cover, and
 wherein the rear cover is detachably coupled to the case, and the front cover is connected to the rear cover and is openable and closable. 
 
     
     
       10. The pump motor of  claim 9 , wherein the front cover includes a front surface, a top surface bent from the front surface, and a right surface and a left surface bent from the front surface,
 wherein one end of the top surface is rotatably connected to an upper end of the rear cover, and, 
 wherein when the front cover is opened, the top surface shields a rear surface of a moisture blocking member. 
 
     
     
       11. A washing machine comprising:
 a main body provided with a water tub; and 
 a pump motor configured to discharge washing water that is accommodated in the water tub, 
 wherein the pump motor comprising: 
 a case: 
 a socket part disposed in a portion of the case and provided with a terminal part thereinside; and 
 a cover part detachably coupled to the case and configured to open and close the socket part, and 
 wherein the terminal part includes a first terminal and a second terminal protruding from the case, and 
 wherein the socket part includes at least one barrier partitioning between the first terminal and the second terminal. 
 
     
     
       12. The washing machine of  claim 11 , wherein the socket part comprises at least one drain hole provided in a lower portion thereof. 
     
     
       13. The washing machine of  claim 12 , wherein the socket part comprises a plurality of drain holes with the at least one barrier in between. 
     
     
       14. The washing machine of  claim 12 , wherein the socket part comprises an inclined surface inclined toward the at least one drain hole. 
     
     
       15. The washing machine of  claim 11 , wherein the socket part comprises a moisture blocking member configured to block moisture from flowing into the socket part. 
     
     
       16. A pump motor comprising:
 a case: 
 a socket part disposed in a portion of the case and provided with a terminal part thereinside; and 
 a cover part detachably coupled to the case and configured to open and close the socket part, 
 wherein the socket part comprises at least one drain hole provided in a lower portion thereof. 
 
     
     
       17. The pump motor of  claim 16 , wherein the socket part comprises an inclined surface inclined toward the at least one drain hole. 
     
     
       18. The pump motor of  claim 16 , wherein the terminal part includes a first terminal and a second terminal protruding from the case, and
 wherein the socket part includes at least one barrier partitioning between the first terminal and the second terminal and a plurality of drain holes with the at least one barrier in between.
